Daim ntawv thov teb ntawm hydrogen sulfide gas detectors
1. Nyob rau hauv kev lag luam kev nyab xeeb: Hydrogen sulfide yog ib tug heev toxic thiab flammable gas, xws li nyob rau hauv petrochemical nroj tsuag, thee mines, thiab lwm qhov chaw. Hydrogen sulfide leakage tuaj yeem ua rau tawg thiab ua rau muaj kab mob lom. Lub tshuab hluav taws xob hydrogen sulfide tuaj yeem siv los saib xyuas qhov concentration ntawm hydrogen sulfide roj nyob rau hauv ib puag ncig ntawm lub sijhawm tiag tiag, kuaj xyuas cov dej xau raws sijhawm, thiab tshaj tawm lub tswb kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm.
2. Kev nyab xeeb ntawm cov mines: Feem ntau muaj kev pheej hmoo ntawm hydrogen sulfide gas leakage hauv mines, uas ua rau muaj kev hem thawj rau kev nyab xeeb ntawm cov miners. Lub tshuab hluav taws xob hydrogen sulfide tuaj yeem siv los saib xyuas cov pa roj hydrogen sulfide hauv cov mines, tshawb xyuas cov pa roj pa phem heev, thiab ua kom muaj kev nyab xeeb ntawm cov miners.
3. Organic synthetic chemistry: Hydrogen sulfide gas muaj ntau yam kev siv hauv cov organic synthetic chemistry. Piv txwv li, hauv qee qhov kev cuam tshuam cov organic, hydrogen sulfide gas yog tus neeg sawv cev txo qis. Lub hydrogen sulfide gas detector tuaj yeem pab cov kws tshawb fawb txog tshuaj hluavtaws los saib xyuas qhov concentration ntawm hydrogen sulfide roj hauv cov tshuaj tiv thaiv hauv lub sijhawm, ua kom muaj kev tswj hwm ntawm cov tshuaj tiv thaiv thiab kev lees paub ntawm cov khoom zoo.
Hauv cheeb tsam kev tsim kho hauv nroog; Hydrogen sulfide feem ntau pom muaj nyob rau hauv cov cheeb tsam qis xws li cov kav dej phwj hauv nroog, pits, septic tanks, cov kav dej phwj tuaj, cov twj tso kua mis pulp, thiab lwm hom fermentation tanks thiab zaub pickling tanks. Muaj qhov ua tau ntawm fermentation thiab tiam ntawm hydrogen sulfide nyob rau hauv cov cheeb tsam no. Tsis tas li ntawd, cov cheeb tsam no muaj qhov cua tsis zoo piv rau sab nraud, thiab nws tseem nyuaj rau kev ua tiav qhov cua, uas tsim cov xwm txheej zoo rau kev sib sau ua ke ntawm hydrogen sulfide.
Tsis tas li ntawd, H2S roj yog dav siv nyob rau hauv tshuaj ntsuam xyuas, hlau refining, muaj cov neeg ua hauj, tshuaj tua kab fluorescence, tshuaj, leej faj thiab volatile sulfur npaj, organic synthesis ntawm txo cov neeg ua hauj.
Covtsau H2S gas detectoryog siv los xyuas qhov concentration ntawm H2S roj nyob rau hauv cov huab cua thiab tso saib nws nyob rau hauv lub sij hawm. Nws txais yuav ib txoj kev diffusion sampling thiab txhawb nqa 4-20MA/RS485 MODBUS cov zis. Nws txuas nrog DCS/PLC lub hauv paus tswj hwm qhov system thiab tso lub tswb lossis txuas nrog lwm yam khoom siv xws li kiv cua thiab solenoid li qub thaum cov roj concentration nce mus txog qib txaus ntshai.
Yuav ua li cas rau nruab H2S roj ntes
1. Yog hais tias qhov ceev ntawm hydrogen sulfide roj yog siab tshaj ntawm cov huab cua, lub installation qhov siab ntawm hydrogen sulfide gas detector yuav tsum yog 0.3-0.6m nyob rau hauv pem teb (los yog pem teb).
2. Nyob rau hauv cov cheeb tsam uas tsis muaj kev cuam tshuam, kev co, los yog muaj zog electromagnetic cuam tshuam, hydrogen sulfide gas detectors yuav tsum tau nruab nrog ib tug clearance ntawm tsis tsawg tshaj li 0.3m nyob ib ncig ntawm
3. Yog hais tias lub ntiajteb txawj nqus ntawm H2S roj ntau dua li ntawm huab cua, lub ntsuas roj yuav tsum tau nruab rau ntawm qhov deb ntawm (30-60) cm ntawm hauv av, thiab lub sensor txoj hauj lwm yuav tsum tig mus rau hauv qab.
Thov tsis txhob nruab rau hauv cov chaw hauv qab no
1. Qhov chaw ncaj qha cuam tshuam los ntawm chav thiab roj fumes;
2. Cov chaw uas muaj cua ntws siab xws li cov khoom siv cua, cua kiv cua, thiab qhov rooj;
3. Cov chaw uas muaj cov dej vapor thiab cov tee dej siab (qhov txheeb ze ntawm cov av noo ntau dua lossis sib npaug li 95% RH);
4. Qhov chaw muaj qhov kub thiab txias hauv qab -20 degree lossis siab dua 50 degree ;
5. Cov chaw muaj zog electromagnetic teb.
